Popup Ad Filter works at the low level in the Internet Explorer engine - stopping a potential ad in its tracks even before it downloads.

Popup Ad Filter also keeps a log of all the sites it has disabled pop-ups from. However if you are exploring the site with necessary pop-ups, just press the control key to temporarily disable the Popup Ad Filter. You can also give it a list of sites at which pop-ups should be enabled (such as your online banking site, etc.).
